Answer:

$450

Step-by-step explanation:

We know that the washer costs $51 more dollars than the dryer.

The washer costs x+51

The dryer costs x

So to simplify this we can do this equation:

2x+51=951

Substitute and simply the equation, and you should get this:

2x=900

x=450

Hope this helps! :)

$900

Step-by-step explanation:

if the washer and dryer combined equal 951 and the washer itself equals 51 then all you need to do is subtract to get the cost of the dryer alone.

Please help me thank you

Answer:

x = 6

Step-by-step explanation:

First, separate the problem into $-\frac{2x}{3} +9=\frac{4x}{3} - 3$

Then, Subtract 9 from both sides of the equation. $-\frac{2x}{3} +9-9=\frac{4}{3} * x - 3-9$

Simplify. $-\frac{2x}{3}=\frac{4x}{3}-12$

Multiply 3 to each side, which will give you -2x = 4x - 36

Subtract 4x from each side -2x - 4x = 4x - 36x - 4x

Combine like terms: -6x = -36

Divide both sides by -6

Your answer should be 6

Answer:

8π in

64π mm²

Step-by-step explanation:

The circumference of a circle is equal to 2πr, where r is the radius.

2π(4) = 8π ≈ 25.132

The area of a circle is equal to πr²

π(8)² = 64π ≈ 201.062

Or the past 100 years, the average high temperature on october 1 is 78° with a standard deviation of 5°. what is the probability

valina [46]

Answer:

The probability is 0.683

Step-by-step explanation:

To calculate this, we shall be needing to calculate the z-scores of both temperatures

mathematically;

z-score = (x-mean)/SD

From the question mean = 78 and SD = 5

For 73

z-score = (73-78)/5 = -5/5 = -1

For 83

z-score = (83-78)/5 = 5/5 = 1

So the probability we want to calculate is within the following range of z-scores;

P(-1 <z <1 )

Mathematically, this is same as ;

P(z<1) - P(z<-1)

Using the normal distribution table;

P(-1<z<1) = 0.68269 which is approximately 0.683
